Siblings Irresponsible Behavior: AITA for Refusing to Let Them Move Back Home?

One sibling tried to be generous, and it quickly turned into a mess. A 27-year-old man let his 25-year-old sister move in rent-free while she got back on her feet, but her habits did not exactly inspire confidence.

What started as a temporary favor turned into arguments about money, responsibility, and basic respect around the house. After repeated warnings and little change, he told her she could not move back in, even as she insisted she had changed.

Now the family tension is spilling into Reddit, and the comments are not holding back. Was he wrong to finally say no?

I'm (27M) currently facing a dilemma with my sibling (25F). A few months ago, I allowed my sister to live with me temporarily while she sorted out some personal issues.

She was struggling financially, so I offered her a place to stay rent-free with the condition that she actively works on getting back on her feet. For context, she has a history of being irresponsible with money and lacking accountability.

Initially, things were going okay, but over time, she fell back into her old habits. She refused to look for a job seriously, spent money on non-essentials, and neglected basic household responsibilities.

It became evident that she was taking advantage of my generosity and not making any effort to improve her situation. This behavior started to put a strain on our relationship, leading to arguments and conflicts.

Eventually, I had to have a candid conversation with her about the situation.

Despite my efforts to help her understand the importance of being self-sufficient, she didn't take my advice seriously and continued down the same path. Frustrated and feeling taken advantage of, I made the tough decision to ask her to find another living arrangement and not come back to live with me.

She was upset, accusing me of abandoning her in a time of need. Now she's reaching out, asking to move back in, claiming she has changed.

That decision did not sit well with her.

says the pattern is hard to ignore.

This is also like the AITA where someone refused to share their adopted puppy with their ex.
